About Tikkurila Hydrosol Primer
A nano particle sized acrylate wall primer ideal for stabilising new or previously treated interior or exterior masonry surfaces in residential, commercial and storage premises. Hydrosol Primer penetrates well into the surface, strengthens the substrate, evens out its absorbency and improves the adhesion of the finishing paint.
Surface Preparation
Surfaces must be clean, dry, and free from grease, dirt, oil, wax, rust, loose material and surface contamination. Use Tikkurila products for mould removal and cleaning. Repair surface defects holes and cracks with a good quality repair filler or mortar.New plastered surfaces need to left at least 6-8 weeks to cure and dry out before treatment.
Application and Thinning
Recommended method, apply with a low-pressure spray ("Backpack garden sprayer"). Hydrosol can also be applied by brush or roller. Apply Hydrosol Primer un-thinned For very porous or chalky surfaces apply, thinned with water (ratio 1:1) To gauge whether there has been sufficient primer applied can be assessed when the primer has absorbed into the substrate’s pores and does not leave a glossy, varnish like film on the surface. The primed surface can be treated the next day. Do not apply Hydrosol Primer on a wet or non-absorbing surface.
